July 10, 2018 — 3M recently announced it has developed two new tapes: the fire and water barrier tape and the smoke and sound tape, both of which meet ASTM and NFPA requirements.  

The company says these tapes are the first of their kind and contain self-adhered membranes that provide an elastomeric seal. Engineered with a pressure-sensitive adhesive that sticks to a variety of construction substrates, including damp surfaces, at high and low temperatures, each tape is designed for specialized functionality and application.

The fire and water barrier tape is ideal for sealing perimeter joints (curtain wall joints) and other construction joints, as well as select through-penetration applications. The tape is recommended for areas that require fire protection and a watertight seal, and has been engineered to prevent the transmission of smoke and sound.

Meanwhile the smoke and sound barrier tape is used to provide a seal against hot and cold smoke, and to help reduce sound transmission. The tape can provide a smoke seal for construction joints and through-penetration applications in non-fire-rated wall and floor assemblies, including smoke partitions and acoustic assemblies.
